Inventor: MOON HEON-HEE
IPC: H04N7/12
Filed: 1992-05-12
Abstract: A system for transmitting and receiving video signals compressed into frequency band blocks, has an adaptive modulation circuit (410 or 450) and an adaptive demodulation circuit (520, 550). The adaptive modulation circuit (410) receives the signal blocks to obtain a block adaptive factor f1 and an index signal ID1, transmits the index signal ID1 therefor to a channel, interpolates the block adaptive so as to obtain a picture element adaptive factor, and selects a final adaptive factor among the block and picture element adaptive factors according to the video signals of the peripheral signal blocks. The adaptive demodulation circuit (520) converts the index signal ID1 into the corresponding block adaptive factor f1, and interpolates the block adaptive factor to produce the picture element adaptive factor, so as to selectively provide the block or picture element factor according to the video signals of the peripheral blocks.

Patent CA-2091289-A1 (CA)
Title: Insect trap
Inventor: REIBLING DOUGLAS J
IPC: A01M1/02
Filed: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE A trap for sap beetles and the like has a container with side walls that diverge from a base thereof.  The container has an elongated bag made of flexible plastic inserted therein.  The support has a mouth with a lip surrounding said mouth and the bag has a closed end and an open end.  The bag is mounted within the support so that a closed end of the bag extends downward beneath said lip in a generally U-shaped configuration.  The bag is formed around the ring into the shape of a truncated cone that extends downward from the lip above the closed end.  There is an opening in the bag through a centre of the ring and the bag is sealed around the lip with a removable cover resting on the lip. The cover contains perforations that are large enough to permit sap beetles to pass therethrough.  The closed end of the bag contains a liquid bait to attract the sap beetles.  When the sap beetles enter the trap through the perforations in the cover and move past the truncated cone into the liquid bait, it is extremely unlikely that they will subsequently be able to escape from the trap. The cover can be removed and the bag containing the bait and the trapped sap beetles can be removed from the container and discarded. A new bag can then be inserted into the container and formed into the shape of a truncated cone around the ring.

IPC: H04Q3/68
Filed: 1993-05-13
Abstract: A method and system for finding a path through a communications matrix represents the assignment of a center stage switch through an input switch to input gates by an input stage array, center stage switch connections between an input stage switch and an output stage switch by a center stage array, and output stage switch connections to output gates by an output stage array, as well as representing idle input switch links to the center stage switches by an idle input array and idle output switch links from the center stage switches by an idle output array. The method and system perform a process of pumping the input stage array, output stage array and center stage array using information in the idle input link array and the idle output link array to determine an optimal center stage switch having both an idle input link between a predetermined input gate and the optimal center stage and an idle output link from the optimal center stage to a predetermined output gate as identified by the idle input link and idle output link arrays. The pumping process relies on the idle input array and idle output array for connection status data. The method and system may be used advantageously with a rearrangeable communications matrix to establish optimal connection configurations during both normal and rearrangement operations.
